Paata,
It appears to me that your question has more to do with PL/SQL than JDBC, so allow me to suggest the PL/SQL:
PL/SQL
Also, the PL/SQL Web page has links to sample code:
http://www.oracle.com/technology/tech/pl_sql/index.html
And you can also access Oracle's "PL/SQL User's Guide and Reference" from here:

Good Luck,
